I know its BMW's official line for the F25 X3 is that the transfer case is a "sealed-for-life" unit and should not be touched, but on two occasions - probably around 2-3 years ago with ~60,000 km (36,000 miles) - they (my local BMW dealer) flushed the transfer case to overcome jerkiness issues particularly with low speed turning. At the time of the second flush when I queried the practice, I was told it was becoming increasingly common with the F25 X3. Have had no problems since then and now up to near 120,000 km (72,000 miles).
